DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an accessory having a locking apparatus according to the present invention, FIG. 2 is a longitudinal sectional view showing a locking operation of the accessory according to the present invention, and FIGS. 3 and 4 are longitudinal sectional views showing unlocking operation of the accessory according to the present invention. In the drawings, a bracelet is illustrated as an example of the accessory.

Referring to FIGS. 1 to 4, the locking apparatus 100 according to the present invention includes a locking housing 110 and a rotary lever 120, which are installed at one end of an accessory body 100′. A locking bar 130 having a locking protrusion 131 is fixed to the other end of the accessory body 100′ in correspondence with the locking housing 110 and the rotary lever 120.

The locking bar 130 is spaced apart from the locking housing 110 and the rotary lever 120. When a user inserts the locking bar 130 into the locking housing 110, the locking bar 130 is locked in the locking housing 110 by a torsion spring 123, which will be described later in detail.

The detailed structure of the locking apparatus 100 according to the present invention is as follows. The locking housing 110 is fixed to one end of the accessory body 100′ and a space section 111 is formed in the locking housing 110.

The rotary lever 120 rotates about a hinge 121 in the space section 111. The rotary lever 120 is partially exposed out of the locking housing 110.

The torsion spring 123 is installed around the hinge 121 of the rotary lever 120 to elastically support the rotary lever 120. A push part 120 a is formed at one side of the rotary lever 120 while being exposed out of the locking housing 110, and a locking protrusion 120 b is provided at the other side of the rotary lever 120. An inclined guide surface 120 c is formed at an end of the locking protrusion 120 b.

One end of the push part 120 a is bent toward the space section 111 of the locking housing 110. If the user pushes the push part 120 a to unlock the accessory, one end of the push part 120 a slidably makes contact with an inner wall W of the space section 111 of the locking housing 110 (see, A of FIG. 3).

A stopper 125 is provided at the other end of the push part 120 a to restrict the rotation of the rotary lever.

Meanwhile, the locking bar 130 having a locking protrusion 131 is fixedly provided at the other end of the accessory body 100′. An inclined guide surface is formed at an end of the locking protrusion 131.

The inclined guide surface 131 a of the locking protrusion 131 and the inclined guide surface 120 c of the locking protrusion 120 may allow the locking bar 130 to be easily inserted into the space section 111 when the locking bar 130 is inserted into the space section 111 of the locking housing 110.

If the user inserts the locking bar 130 into the locking housing 110, the locking protrusion 131 of the locking bar 130 is locked with the locking protrusion 121 of the rotary lever 120 due to elasticity of the torsion spring 121, so that the accessory is locked (see, FIG. 2).

In contrast if the user presses the push part 120 a to unlock the accessory, the rotary lever 12 rotates about the hinge 121, so that the locking protrusion 131 of the locking bar 130 is separated from the locking protrusion 121 of the rotary lever 120, thereby unlocking the accessory (see, FIGS. 3 and 4).

Hereinafter, the locking/unlocking operation of the locking apparatus for the accessory according to the present invention will be described.

In order to lock the accessory 100 after wearing the accessory 100, the user inserts the locking protrusion 131 of the locking bar 130 into the space section 111 of the locking housing 110.

When the locking bar 130 is inserted into the space section 111 of the locking housing 110, the inclined guide surface 120 c of the locking protrusion 120 b and the inclined guide surface 131 a of the locking protrusion 131 allow the locking bar 130 to be easily inserted into the space section 111 of the locking housing 110.

As the locking bar 130 has been inserted into the space section 111 of the locking housing 110, the locking protrusion 131 of the locking bar 130 is locked with the locking protrusion 121 of the rotary lever 120 due to elasticity of the torsion spring 123 (see, FIG. 2).

Meanwhile, when it is necessary to unlock the accessory 100, the user presses the push part 120 a of the rotary lever 120, so that the rotary lever 120 rotates about the hinge 121 (see, FIG. 3).

Thus, the locking protrusion 131 of the locking bar 130 is separated from the locking protrusion 121 of the rotary lever 120. In this state, the user can take the locking bar 130 out of the space section 111 (see, FIG. 4).

If the user releases pressing force applied to the push part 120 a, the rotary lever 120 returns to its initial position while being rotated about the hinge 121 due to elastic restoring force of the torsion spring 123 (see, FIG. 2).

As described above, if the user inserts the locking bar into the locking housing, the accessory is locked due to elasticity of the torsion spring, and the accessory is unlocked if the user presses the push part of the rotary lever. In other words, the locking apparatus has a simple structure, so the locking/unlocking operation of the locking apparatus can be simplified without deteriorating the aesthetic appearance of the accessory, thereby improving reliability of the product.

In addition, since the locking structure of the accessory can be simplified, the manufacturing cost for the accessory can be remarkably reduced.
